Be it known that I, BURNHAM C. STICK- NEY, a citizen. of the United States, residing in Rutherford, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in 'Iypewrit-` ing Machines, of which the following is 'a The present invention relates tosounddeadening casingsfor typewriting machines, and more particularly to'the window thereof through which the printing is visible to the operator.' V'Ihis is a division of application Serial No. 531,858,5:iiled January 24, 1922 l(now Patent N 0. 1,553,480, dated Septomber 15, 1925). y

In a 4'casing of thisqcharacter, the top, is ordinarily arched upwardV from 'the rear to accommodate the carriage of the typewriting machine; and, to eliminate unnecessary bulk and weight, it isthencesloped downward and forwardfto thefront of the casing. This slope is also desirable to bring the lower' edge of. a rectangular window opening Well below the line of vision to the printing point. rlfhe Window has usually Vbeen a Hat window set .in`v the opening of this'forwardly-sloping part ofthe topiof the casing. It has been found-that lights, when in certain positions, and ,usually above the typewriterdesk or stand, Aare objectionably reflected into the eyes of the operator by such a window; and various expedients, such as having the window-pane angularly adjustable, within moderate, limits, lhave heretofore been resorted'to for diversion of such objectionable reflections. ,k A ,f f

-It is aniobject of the present invention to substitute, for the flat sloping windowpane, a windowcomprised of a plurality of panes set at an angle to one another, and

set'at such angles that no light, properly positioned with reference vto the voperator and the machine, will be objectionably reilected tothe operator. In the preferred form of the invention, I provide a window with two such panes, onea horizontal pane, which will cause the rays from a light, over the stand or desk, tol be reflected upward, above the loperators line of vision, and the serial No; eeaeid other a vertical pane, which .will cause .any rays reflected therefrom to pass below the operator-s line 'of vision. Either the-ver.- tical or .the horizontal pane may be inthe operators line of-vision ofy thev platen, and

ENT ,olin-VICE.

this application filed septhe other pane wiil. serve to assistinthe il-V lumination of the interior Vof the casing. VGnly the'pane Whichis in the operators'line ofv vision of the platen need be transparent; the'other pane .may betranslucent, and, 'if desire`d,may have a ground outer surface, so that there can ybefnoobjectionable reflection therefrom, regardless of the position ofy the light.. A n n .Y In the present form of theinventiomjthe K window is L-shaped andv preferably inverted so as toextend outwardly from the casiiig. With this arrangement the space inthe casing is not unduly* occupied bythe window,

which space` is casing.

A provision ofIneans whereby the window may be angularly adjusted to divert reflec-I tions-of improperlyY positioned lights. In this connection, itwill be understood Vthat the invention .is not' restricted toa window, the panes of which are set; verticallyand horizontally, or at right anglesto each other, or even toawindow inwhich there are `but two panes. tion, one of the panes need not be. of lighttransmitting material.

otherwise desirable inthe `Fro`m the complete novel disclosure found l in the above-mentionedprior application, -it can` plainly beseen vthat this invention is applicable for an easy and simple arrangement whereby vthe windowfurther object ofl the invention` kthe VIn Asome vforms vof the ,inventhereof may f be l made interchangeable with 'the ordinary flat sloping "window, so that one or the other may be used .according to lighting conditions Or test; or may be designed to be inverted, that is to say, may be set So as to be concaved as well vas convexedwith respect to the outsidefcover whenever occasion demands such modified forms.

Other features and advantages will hereinafter appear.

Inthe accompanying:drawings, i. r Figure' 1 isa View n cross-sectional side shown.

elevation of a sound-deadening typewritercasing embodying the features invention, the platen and the platencarriage 'of the machine being indicated in dotted lines therein. Y

Figure 2 is a front view in cross-section on line 2-7-2 .of Figure 1.

Referring to the drawings, the casing is shown as comprising a body-portion 10 and a cover-portion 11 hinged at 12 to the bodyportion. r1`he casing is preferably provided with fa :sou'nd-deadening lining (not shown). The position of the platen is in-v dicated in dotted lines at 18, Figure 1, on a carriage 14, also indicated in dotted lines. A; slot, not shown which exten-ds longitu dinally of the front wall of the casing, is normally closed by suitabley means not Through the slot may protrude the usual line-space and carriage-release which are not shown, but which may be suitably mounted on the typewriter carriage, and which'move along the slot.

The top of the cover is provided with an opening 18 for avwifndow of yglass or other transparent material, through which the operator may observe the printing on the platen 18. The casing-cover is preferably a casting hav-ing means thereon for con-v trolling the swinging Jof the window within the opening.

The window may comprise a horizontally-di-sposed pane of lglass 2O and a verti` cally-disposed pane 21 both supported on 'the 'flanges V28 and 29 of the pane-'supporting plates 54, vas shown in Figures 1 and 2. To' hold the panes of glass 20 rand 21 to flanges 28 and 29 of plates 54, any conventional `means may be used as by screws 3() having V'heads'V countersu-nk in the glass panes. Packing strips 31 and 32 are preferably inserted between panes 2O and 21 an-d flanges.. 28 and 29 of the plates 54, Vand the packing 31 extends across the top of the front pane y21 `where the pane 2O overlies the same. The rear edge of the horizontal pane 2() has a Lil-shaped strip 45 preferably of metal Vsecured thereto and to the plates 54 by any suitable means. Thus the strip 45 and plates 54 form a frame to support the window-panes 2O Vand V21. Binding strip -45 extends longitudinally of the rear ledge of lthe pane 2O and has formed thereon a rounded bead 46,l which is set into a correspondingly rounded recess v4'? formed in cover 11 at the upper edge of the `opening 18. Forr holding the bead 46 inthe recess 47, there are provided guards or lingers 48, of which there are preferably two, one near each end ofy the window. The guards 48 are shown as flat metal pieces secured -to the cover 11 by screws orl rivets 49, and adapted'to 'be lswung or lifted, so that the bead 46 may be removed from its seat 47 of the present when it is desired to remove the window bodily from the cover. The bead 46 and its seat 47 being round permit of easy angular adjustment of the window; and the guards 48 terminate 'short .of fthe neel. formed by the bead 46, so as notto interfere with such angular .mouement of the window.Y f Y In order that `the window mayy 4have ample angular movement withoutV opening joints in the casing, the forward reach of .the window-frame opening ifs;A provided with a zwide concaved flange 50 curved on an arc struck from the pivot-point at 46, and preferably lined with a strip 51 yof sounddeadening material, such as felt, into which the lower vedge ofV the' vertical .pane 21 may set in any yangular position of the win-dow. Ags shown in Figures k1 Vand 2, the side Vreaches of the window-frame opening also have flanges 52, wide enough Vand of such shape as to prevent opening of joints .at the sides of the window, and the flanges 52 are also provided vwith strips 530i" fel-t. l kTo support Aand secure the window in adjusted position, suitable means may be provided f as from -plates 54. The ears 55 may be perforated, as at 56,`to receive a reduced portion or neck 57 of the window-adjusting thumb-screws. l58 which are threaded into lugs 59 of the casing cover 11. For turning the adjusting screws 58 a knurled Vhead may be provided, and the siou'lder formed by the reduced portion or neck 57l of the screws 58Vis arranged to .cause the window to lift or lower when the screws 58 are turned, and the perforations 56 in ears 55 are dcsigned to allow for the angular `movement of the window structure. One or two adjusting screws 58 may be used as required. In thev disclosed arrangement the operator may lobserve the printing ofthe platen through theY `vertical pane 21, and the light rays striking down on the pane 21 will not be reflected into ther operators eyes. v With the lights situatedin suitable positions, a transparent or polished pane 2O would reflect the rays upward in a direction in which they would not strike the operators eyes. Inthe event that a distant overhead light, in front ofthe typist, is reflected from the horizontal pane 2O it would annoy the operator. This objec# tionable refliection may be veliminated by swinging the window angularly, "in one or the other direction, by means Vof the adjusting'screws 58 inthe manner described, thus Areflecting the light rays above orbe low the normal line of vision to the printing point.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
